At CES 2026 in Las Vegas, Nimble introduced four new options as alternatives to Apple’s AirTag, which is priced at $24 on Amazon. Each of these new trackers uses similar technology but features distinct designs. The collection includes a keychain tracker that resembles the AirTag, along with a luggage tag, a passport holder, and a wallet designed solely for cards, which doesn’t include a coin section.

Compatibility and Unique Features

These trackers are compatible with both Apple’s “Find My” network and Google’s Find Hub, allowing users to connect them easily whether they have an iPhone or an Android device. One standout aspect of these trackers is their integrated battery. It offers the convenience of wireless charging via a Qi pad, and it’s also a novel cellulose-based battery. This so-called “paper battery” has been created by Flint Labs and is currently in mass production.

Battery Specifications

The battery resembles a typical coin cell but is remarkably slim, measuring just under 0.04 inches thick. For comparison, the CR2032 coin cell found in the Apple AirTag has a thickness of 0.13 inches. Flint Labs claims that this cellulose-based battery is more eco-friendly than traditional lithium batteries and even asserts that these batteries are biodegradable, though specific details regarding their materials have not been disclosed.

Nimble has not shared information about how long these batteries will last or their overall lifespan in the new trackers. Additionally, there has been no confirmation on the release date for these four new trackers that utilize Flint Labs’ batteries, and the official pricing remains uncertain as well.
